Yun Liu   I am a professor at the College of Computer Science, Nankai University. Previously, I served as a senior scientist at the Institute for Infocomm Research (I2R), A*STAR. Prior to that, I was a postdoctoral researcher in the Computer Vision Lab at ETH Zurich, working under the supervision of Prof. Luc Van Gool. I obtained both my bachelor's and doctoral degrees from Nankai University in 2016 and 2020, respectively, under the guidance of Prof. Ming-Ming Cheng. My research interests focus on computer vision and deep learning.   VAGRANTLYUN [AT] GMAIL [DOT] COM               Google Scholar               GitHub
